Money really isn't that big of a deal.
E-cig selection is purely personal. If money is really not that big of a deal, I would jump to one of the high-end customized mods. I have the NPro. It works, and has a semi decent battery life for a commercial "mini". It's bigger around than a camel wide, so it takes a little getting used to the mouth feel. The carts won't last very long, so unless you ordered a ton (I doubt) or ordered e-liquid, you are going to run out pretty quick.
If you are just interested in seeing if you like the e-cig experience, the NPRO is just as good as any, assuming you are prepared to throw it out after a month or so. Think of it as a slightly more expensive disposable to test the waters, and you'll be ok. After that, you'll probably be looking for a different model or a mod.
My only caution is to not invest heavily in any particular technology (Whether it's 510, 901, mod or NPRO) until you have a feel for what you like / don't like about the NPRO (or whatever you choose as a first). Each e-cig has its own strong and weak points, hence the common situation of people owning 4-5 different mods.
Once you have a feel for what you want (more vapor, longer battery life, longer cartridge life, smaller, bigger, prettier, more cigarette-like, less cigarette-like, easily available parts, whatever) you can come back and do some research on the different models and styles and make a more informed choice. Regardless of the initial model chosen, it will give you a baseline to refine your preferences from.
